(Cl. Bile-40) 13 Claims.

The invention relates to razors of the. so-called.

magazine type and more particularly toa con.

struction that may be used with blade packs hav-,

ing the characteristics of those tobe-described.

One of the objects of the invention is a razor with which can be used a blade pack of compact form and make-up that utilizes inexpensive containers or wrappers.

Another object is to enable the user to-loadthe magazine with loose blades which however are provided with means for preventing easy dislodgment. of one from another and whereby the pile of blades will be maintained in fixed position in the magazine except as they are ejected one by one as needed from the magazine into the shaving head of the razor.

Other objects will appear. in the course of thedescription of the invention.

Fig. 10 is a view illustrating the method of introducing a blade into the head of the razor;

Fig. 11 is a view showing the positions of the parts when the blades of the pack have. been exhausted;

will be presently explained. Each blade is therefore definitely located with respect to blades adjacent to. it, although since the nubs and indentations. are of approximately spherical contour a slight force is suflicient to dislodge them and to cause the blade towhich the force is ap:

plied to slide on the. one with which it contacts,

The contour of the indentations and nubs is however not. invariable, the particular contour shown being selected merely because of its metal-working advantages coupled with the fact that it satisfactorily functions to locate the blades with respect. to each other and at the same time offers a yielding instead of a positive resistance todislocation. However, it will becomeapparent as the description continues that, while it should be possible to dislodge a blade for'lengthwise movement in .one direction, it may if desired be positively prevented .against dislodgment in the opposite direction. The. manner in which the nubs .and indentations function is illustrated in Figs, 2,. 3, and 4. The numberof blades in the stackis a matter of choice, although limited of course by the capacity of the chamber of the razor into which they are .to be inserted.

The stack ,of blades .preferablyrests upon a plate l2..(Fig..5). .providgd, as in the case of the Fig. 12 is a view showing the head ofthe razor v in closed or non-shaving position;

Fig. 13 is a view showing the head. of the razor in shaving position.

Referring more in detail to the drawings, a preferred type of blade that may be used to make up the pack is illustrated in Figs. 2, 3, and l. The blade shown is of a well-known conventional shape but is distinguished from such blades'in that it is provided with two depressions or indentations l6 and H, the process of producing these indentations (which may be accomplishedv by the use of a punch and die) creatingnubs on the opposite side of the blade. The blades are all alike, and the nubs are similarly and. uniformly positioned on all of them so that, when the blades are stacked or piled, the nubs of each blade nest in the indentations of the blade next below it, except of course in the case of the bottom blade, the nubs of which nest in the bottom plate as t is. (Fig. 5).

blades, with indentations indicated by the numerals I3 and lllocated to register with the nubs, on the bottom. blade of the. stack, The tongue. [,5 projecting fromone end. of the plate tips slightly down (as viewed .in the drawings) and likewise the opposite end I6... In addition, two tongues. I1, l1. are struck. downwardly to servev as, abutments to cooperate with the lugs l8, l& projecting laterally. from the lifting spring The functions performeed by the bottorn-plate and the spring will be later explained. In assembling, the stack of. blades rests on-the plate -I2, the nubs of the bottom blade registering with the indentations i3 andl l of the plate.

To retain the stack and the plate in assembled condition whereby it will resist forces tending to dis-assemble it, I provide the, cliptfi (Figs. 1 and 6) whereby, it will resist casual forces, which is of resilient material, such as steelor hard brass, the clip being (as inthe case of the blades) provided with indentations and corresponding nubs 2!, 2|, although in this case only thenubs function. These nubs register with the indentations in the top blade of the stack. Theclip is of U-shape as shown with the legs of the U normally turned inward toward each other so that, when stressed to grip the stack as shown, the latter will be tightly clamped. The bottomleg of the clip is provided with a longitudinal groove 22 into which the nubs of the plate 12 project and whereby the lower leg of the clip is maintained in a fixed position laterally.

The razor combines a shaving head generally designated by the letter A mounted on a post projecting from a hollow handle, generally designated by the letter C, which serves as a magazine for containing the blade stack and also the mechanism for ejecting blades therefrom. It consists essentially of an elongated boxlike structure closed at one end except for the presence of the blade-ejection orifice 24 and open at the opposite end to permit the bladeinserting and blade-ejecting mechanism to be operated.

A blade stack container indicated generally by the letter B is slidably encased in the chamber within the handle. This container is essentially a box with the sides 25 and 26 and the end Wall 21, the top being open and the bottom being apertured as at 28 to permit the lifting spring to free itself and drop to thebottom of the container when the latter is withdrawn from the chamber in which it is enclosed. To explain, it is to be noted that the lifting spring 19 pivotally engages the ends of the side walls of the box by means of the shoulders 29, 29. When the container is within the chamber, the free end 30 of the lifting spring rests on the bottom of the chamber and the spring bows upwardly as shown in Fig. 11, where the container is emptied of blades and, as shown in Fig. 4, where a full stack of blades is within the container. The normal shape of the spring when in an unstressed condition is approximately as showin in Fig. 5. When the blade container is withdrawn from the chamber, the free end 30 of the lifting spring drops through the aperture 23 in the bottom of the container and down over the end of the bottom wall of the chamber, and therefore its presence does not interfere with the insertion in the container of a stack of blades. Clearance is provided between the upper edge of the end wall 21 and the top wall of the casing in order to permit of the passage of a blade and also of the plunger from the magazine through the blade ejection orifice 24. This end wall is centrally notched as shown in Figs. '7 and 11 so that the nubs on the blades will pass freely through.

A closure for the container and also for the open end of the razor handle is supplied by the block 3| pivoted to the container by the trunnions 32, whereby, when the block carrying with it the container is withdrawn to the position shown in Fig. 6, it drops down or may be swung down to permit of the insertion in the container of a blade pack also as shown in Fig. 6. It will be observed that the block 3! has a slightly inclined surface 33 (Figs. 4 and 6), the purpose of which is to insure a certain and easy entrance when the block (with the container) is moved into the chamber from the position shown in Fig. 6 to the position shown in Fig. 4. The plate 34 retained in position by the rivets 34a. and 34b is simply an expedient for establishing a hinged connection between the block 3| and the blade container.

Ejection of blades one by one through the blade-ejection orifice 24 is elfected by means of the plunger 35, which is slidably mounted within the handle so that it can be reciprocated between the positions shown in Figs. 4 and 11 in line with the blade-ejection orifice. It is channel-shaped, the edges of the flanges of the channel sliding along the upper edges of the container, and rear support and freedom of motion are permitted by the fact that it slidably rests on the block 3|. To limit its rearward stroke, an outwardly projecting spring tongue 36 is provided, which on withdrawal of the plunger abuts against the indentation 36a (Fig. '7) in the inside of the Wall of the chamber. The container itself may also be provided with a similar spring tongue 31 which enters an indentation in the wall of the chamber and operates in a similar way to limit the extent to which the container may be withdrawn from the chamber.

The shaving hcad (see Figs. 4, '7, and 9) is pivoted to the post 23 so that it can be swung to the position shown in these figures to receive a blade and then to a position perpendicular to the post for shaving purposes. It consists essentially of a bottom plate 38 and a blade clamping plate 39, which may be angular extensions of the plates 40 and 4| through which the pivoting screw 42 passes, whence it is threaded in the post. The usual guard 43 is, of course, provided. In the blade-supporting surface of the bottom plate 38 there is provided a longitudinal groove 44 in which the nubs of a blade travel in the course of being injected into the shaving head. The position of this groove latblades are all uniformly positioned in the head.

Of course, on the other hand, the position of the groove may be first fixed and then the blades may be manufactured with the nubs positioned to correspond with the position of the groove.

The groove 44 registers with the groove 45 in the end wall 46 of the handle and thus the nubs of the blade being ejected travel in it and thence into the groove 44. To properly guide the blades into the groove 45 its entrance may be slightly widened as shown at 41. It will be observed (see Fig. 7) that one corner of the container is formed to exhibit a diagonally extending facet, as shown at 48, and that (see Fig. 6) the block 3| is provided with a flange 49 of triangular section.

. Thus, only the extreme ends of the cutting edge of a blade in the container can contact with the wall of the container, which is course is desirable to insure that their edges shall not be injured.

The corners of the blades themselves are preferably cut away as shown in Fig. 6 but not sumciently to permit the blade edge to contact with the side of the container. This is shown in Fig. 7.

By reference to Figs. 1 and 6, it will be understood how the pack may be assembled. The desired number of blades may first be stacked with the nubs of each successive blade beginning with the top blade and nested in the indentations of th blade beneath and (if single edge blades) with the edges all on one side of the pile. The pile may be then placed on the bottom plate l2 with the nubs of the bottom blade nested in the indentations I3 and M of the plate and with the tongue l5 at that end of the pack which first enters the blade stack container as the magazine is being loaded (see Fig. 6). The clip or clamp (see Fig. 1) is then applied so that nubs on the upper leg of the U nest in the indentations in the uppermost blade and the nubs on the plate I2 register with the groove 22 on the lower leg of the U. The legs of the U point in the same direction as does the tongue 5. The blade stack container having been fully withdrawn as shown in Fig. 6 and the closure block 3| being out of the way, the pack is then inserted in the container. The clip is then Wholly withdrawn (to be discarded if desired), the cooperating nubs on the upper leg being readily freed fromthestaok and;

leaving the stack together with the plate I2 in the container. stack as the clip is withdrawn, the container is provided with a stop ED-against whichthe blade stack abuts as the clip-is withdrawn, tendingto' will prevent withdrawal of the stack although it does not interfere with withdrawal ofthe clip. The closure block 3| is relieved as shown at Ma so that it can be closed without interference from the stop. The clip having been withdrawn, the

blade stack container, together with the closure block M (the latter being swung up in the process), is driven into th chamber to the positionshown in Fig. 4. As this takes place, the spring i9 is dragged along the container, its free end railing along the bottom of the casing, the result being that it is flexed from its normal shap as shown in Fig. 5 to a nearly flat shape; which causes a resilient upward pressure tobe'exerted against the blade stack. The uppermost blade of the stack is therefore always pressing against the plunger or, against'th top wall of the casing (i. e., in line with the blade ejection orifice) when the plunger is withdrawn As blades'are fed one by one from the stack, the stressed spring follows upwardly until the last blade'has been ejected. In order to insure that the last blade shall not be dragged backwardly by the friction of the plunger as the latter-is withdrawn, the lugs l8, I!) may be provided on the spring against which the tongues H, I? abut, there being enough flexibility in the spring to allow the lugs !8, I8 to travel upwardly in a perpendicular plane.

Actual ejection of the topmost blad of the stack is effected by first fully retracting the plunger, whereupon the topmost blade rises to alignment. with it and withthe ejection orifice', and then advancing the plunger to th position shown in Fig. 4. Thi action dislodges the topmost bladefrom theone beneath it, and it is drivenrinto shaving position in the head, guided to proper relation with the guard becauseits path is fixed by the nubs traveling in grooves 44 and 45. If it is desired then to use'the implement for shaving, the shaving head is swungto a position crosswise of its supporting post.

The blades all maintain their positions fixedly with respect to each other by virtue of the nesting of the nubs and indentations, a condition which is maintained by the pressure of the lifting spring l9.

When the bottom blade of the stack has been ejected, the bottom plate H. has risen tothe top of the chamber as shown in Fig. 11. On withdrawal of the closure block and blade stack con-. tainer, the bottom blademay'be dropped out or manually removed. It has previously been noted that th ends of the bottom plate are tipped downward slightly. This is to prevent its being ejected through the blade discharge orifice. If it is attempted toso eject it, the tip of the plunger rides over the end It insteadcf abutting with it as in the case of a blade. But even if there is any tendency to eject it. through the orifice by reason of frictional contact between it and the plunger, the tipped-down tongue [5 abuts To prevent withdrawal of-the against the end wall of the blade stack container which positively prevent it from passing into the blade ejection orifice.

Figs. 12, 13, and 14 illustrate an adaptation of the invention to the type of razor with which a separate magazine is employed. The parts indicated generally by the letter E are in all respects similar to the parts indicated by the letter C in Fig. 4. However, in place of the shaving head mounted on the post as shown in Fig. 4, there is provided an aligning finger 5! which is designed to enter an aligning slot 53 in the shaving head 52 and position the magazine and the shaving head with respect to each other so that a blade ejected from the magazine enters the blade channel in the shaving head. This shaving head as in the case of that shown in Fig. 4

has a bottom plate 38 and a blade clamping plate 39 and guard 43, together with a groove 44, in the bottom plate precisely as in the case of the permanently ailixed shaving head. Razors of this type are as shown in Rodrigues United States Patent No. 1,969,945, issued August 14, 1934.
